Chapter 4: Problem 79

Solve the equation. $$ 9-y=4 $$

Short Answer

Expert verified
The solution to the equation is \(y = 5\).

Step by step solution

01

Understand the problem

The equation given is \(9 - y = 4\). The aim is to solve for 'y', which means isolating 'y'.
02

Transpose

Transpose '-y' to the right side of the equation and '4' to the left side. In this process, change the signs. So it will become \(9 - 4 = y\).
03

Simplify

Simplify \(9 - 4\) to find 'y'. So, \(y = 5\).
